Description

The SFH757 is a low-cost transmitter for simple optical data transmission with polymer optical fiber. This very robust 650nm LED can be used for speeds up to 100MBd.

The transparent plastic package has an aperture where the the 2.2mm fiber-end can be inserted and fixed with glue. This easy coupling method is extremely cost-effective.

The SFH757 is a kind of plastic fiber optic transmitter diode. The typical applications include household electronics, power electronics, optical networks and light barriers.

There are some features of SFH757 as follows: (1) high speed transmitter for about 50 Mbit/s up to 100 Mbit/s (with peaking circuit); (2) 2.2 mm aperture holds standard 1000 micron plastic fiber; (3) no fiber stripping required; (4) molded microlens for efficient coupling.

What comes next is about the absolute maximum ratings of SFH757. (1): VR (reverse voltage) is 3 V; (2): IF (forward current) is 50 mA; (3): IFSM (surge current (t10 s, D=0)) is 50 mA; (4): Ptot (power dissipation) is 120 mW; (5): RthJA (thermal resistance, junction/air) is 450 K/W; (6): Tstg (storage temperature range) is from -40 to +100; (7): Top (operating temperature range) is from -40 to +80; (8): Tj (junction temperature) is 100; (9): TS (soldering temperature (2 mm from case bottom, t 5 s)) is 260.
